Be it known that we, MARQUETTE A. Hanny and WALTER I. Kinn, citizens of the United States, residing at Chicago, in the county oit Cool; and State of Illinois, have` invented a certain new and useful limprovef ment in Lighting Fixtures, of which the tollowing is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to lighting fixtures and especially to a lighting fixture adapted for use upon anuprght piano or similar instrument. l j j One of the objects ot the invention is to provide a practical and effective lighting tixture oi' the class specified.

Another object 'ot' the invention is to arrange for theautomatic control of the light, so that it may be 1 lighted :and put out automatically.

Another object of. the invention is to arrange for the adjustment ot the lixture so that the light maybe placed 1n an advanto be lighted. 4

Another object ot the invention is to permit the control of the light to be brought about automatically bythe adjustment of the fixture, permitting the light to be lighted vwhen the fixture is adjusted in one position and to be put. out when the fixture is adjusted .in another position.

Another object oit the :invention is to secure the :foregoing and other desirable results ina simple `and expeditious manner.

`ln the accompanying drawings Fig. 1 is a view partly yin elevation and partly in vertical section of a portion ot a piano Orothcr instrument vprovided with a lighting lixture embodying our present invention;

Fig. 2 is a horizontal sectionftakeni on `line 2--2 in Fig. 1.

In the drawings we showan upright member 1 which is `understood to be part of a piano or other instrument or article to which the lighting fixture is to be applied.

The lighting `iixture is shown provided with Va bracket member 2 which is secured to the upright member 1 as by screws 3. A movable or sliding membpr l is arranged within the member 2 and arranged to slide lengthwise of the same in a telescopic manner. At the outer end ot the member l there Specification of Letters Patent. @aight-@d .Wjay 31.5, 192m,

is av vertically arranged tubular member 5 which is firmly secured to said member at and carries at its upper end a shade 6 in which is arranged an electric-lighting bulb 7. The insulating wires or conductors 8 and 9 are arranged -within the tubular memhe' 5 and pass out'o't the same through the tubular slide t and thence to a switch 10 which is mounted in a recess 11in` the member 1. The movement of the slide t longitudinally within the tubular extension 2 of the bracket 2, obviously adjusts the light i' ltoward and away from the member 1.

ris a matter ot further improvement, the switch 10 is arranged and connected so that the movement of the slide e with the light T causes the switch 10 to `.uitomatically lightand extinguish said lamp 7, preferably lighting said lamp when it is pulled out and extinguishingit when it is pushed in. To such end the switch 10 consists et a type of switch having a longitudinally `movable plunger 12 mounted on the end ot a spindle 13, on the other end 'ci' which is a `double cone-shaped member la, the member 1li being arranged within a casing made of insulating material andconsisting of two part-s lOfL and 10b. Another member 15 also made `of insulating material, is fitted within the casing 10b and carries a pair ott metal contacts iti- 16, which contact strips 16-16 are mounted on opposite sides oi an aperture 17 in said membcr15. A sliding Contact member 19 is arranged to work within the member 10L and to move toward and `.away trom the member 15 so that said member' 19 may come into contact with the strips 1G and also be separated trom the same. To such end the member 19 is in the torni ot a small metal casing arranged over or around the member 111 and loosely itted over the same so that it may be moved relativelyto said member 141i in a direction lengthwise thereof. ldithin the l casing 19 is a` spring 20 made by arranging .member `la and thereby separate the contact casing member 19 `from the contact strips 16.

When, however, the plunger 12 is in a pulled out or extended position, as shown in Fig. 2,-the spring 2O will slide the member 19 toward the right hand end ot the member 14 and thus press said member 19 against the contact strips 16. ln the lirst instance the lcontacts 1 9 and 16 will be separated and the circuit thereby broken, whereas in the second instance, said contacts will be in Contact with one another and the circuit closed.

ils an arrangement -for permitting the slide 4L to automatically control the connections of the switch 10, a push rod 22 is secured to the plunger 12` and extended into the bracket 2, so that the adjacent end ot the slide 11 will strike against the Arod 22 andthereby push'said plunger 12 inwardly or into retracted posit-ion when said slide if is pushed inwardly within the bracket 2. Also a chain connection 23 is made between the slide et and plunger 12 so that when the slide l is pulled outwardly the plunger 12 rwill also be pulled outwardly and thereby moved to .its outwardly or extended position. Thus the inward movement of the slide 411 and consequently the inward movement oit the lamp 7 will automatically break the circuit running to the lamp and the Outward movement of said parts will automatically cl se said circuit, whereby said lamp will be automatically extinguished and lighted respectively. The lamp circuit is made, it will be understood, by connecting one of the wires 8 and 9 with one ot the contacts 16, the other wire and Contact connected in they usual manner to a source ot' electricity, which connection is not shown in the drawings, but will be understood to be accomplished in the usual manner of extending said conductors 8 and 9 into the casing 10b and connecting the proper one of the same with the contact strips 16, one to each strip.

It will be understood that vchanges and modifications may be made without departing from the spirit ol the invention.
